QScreenCursor - Manages the onscreen mouse cursor in
Qt/Embedded. It provides an implementation of a software
mouse cursor and can be subclassed by hardware drivers
which support a hardware mouse cursor. There may only be
one QScreenCursor at a time; it is constructed by
#include <qgfx_qws.h>

DESCRIPTION
The QScreenCursor class manages the onscreen mouse cursor
in Qt/Embedded. It provides an implementation of a
software mouse cursor and can be subclassed by hardware
drivers which support a hardware mouse cursor. There may
only be one QScreenCursor at a time; it is constructed by
QScreen or one of its descendants.
This class is non-portable. It is available only in
Qt/Embedded. It is also internal - this documentation is
intended for those subclassing it in hardware drivers, not
for application developers.
MEMBER FUNCTION DOCUMENTATIONQScreenCursor::QScreenCursor ()
Constructs a screen cursor.
QScreenCursor::~QScreenCursor () [virtual]
Destructs a screen cursor, deleting its gfxes, cursor
image and under-cursor storage.
void QScreenCursor::move ( int x, int y ) [virtual]
Move the mouse cursor to point x,y on the screen. This
should be done in such a way that the hotspot of the
cursor is at x,y - e.g. if the hotspot is at 5,5 within

the image then the top left of the image should be at
x-5,y-5.
bool QScreenCursor::restoreUnder ( const QRect & r,
QGfxRasterBase * g = 0 ) [virtual]
This is relevant to only the software mouse cursor and
should be reimplemented as a null method in hardware
cursor drivers. It redraws what was under the mouse cursor
when the cursor is moved.
